Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

n8n-nodes-phoenix

An n8n community node to fetch prompts from Arize Phoenix Prompt Management.

It mirrors the Langfuse "Get Prompt" node: retrieve a prompt version by latest, by tag (label), or by version ID.

Installation · Operations · Credentials · Development · Resources

Installation

Follow the community node installation guide.

Install via the package name:

@scale-out-at/n8n-nodes-phoenix

On n8n Cloud / self-hosted: Settings → Community Nodes → Install and enter the package name above.

Operations

Prompt → Get

Retrieves a prompt version. Choose Retrieve By:

| Retrieve By | Inputs | Phoenix endpoint | | --- | --- | --- | | Latest | Prompt Name or ID | GET /v1/prompts/{identifier}/latest | | Tag (Label) | Prompt Name or ID + Tag Name | GET /v1/prompts/{identifier}/tags/{tag} | | Version ID | Prompt Version ID | GET /v1/prompt_versions/{id} |

Returns the PromptVersion payload ({ data: { ... } }) — template, model, invocation parameters, tools, etc.

Variables

Optionally fill Mustache placeholders in the fetched prompt before it leaves the node. Add rows under Variables (an array of Name / Value pairs); each {{Name}} in the prompt template is replaced with its Value.

  • Inner whitespace is allowed: {{Name}} and {{ Name }} both match.
  • Substitution is scoped to the template only — chat messages[].content (string or content-part arrays) and string templates. All other fields (ids, model, invocation parameters, message roles) are left untouched.
  • Single pass: a Value that itself contains {{...}} is not re-substituted.
  • Unmatched placeholders are left as-is. Leaving Variables empty returns the prompt unchanged.

Example: prompt content Hello {{name}}, welcome to {{product}} with rows name = Ada, product = Phoenix → Hello Ada, welcome to Phoenix.

Credentials

Create an Arize Phoenix API credential:

  • Phoenix Base URL — e.g. https://app.phoenix.arize.com (cloud) or http://localhost:6006 (self-hosted).
  • API Key — sent as Authorization: Bearer <key>.

The credential Test calls GET /v1/projects to verify access.

Development

Requires Node.js >=20.15.

npm install
npm run build      # tsc + copy icons to dist/
npm run lint       # eslint-plugin-n8n-nodes-base
npm test           # jest unit tests (variable substitution)

Tests live in test/ and run on every PR via .github/workflows/ci.yaml; results are published as a Unit Tests check with a pass/fail summary.

Local testing: npm link this package into ~/.n8n/custom and restart n8n. See the n8n node dev docs.

Versioning & releases

Releases are automated. Versioning uses GitVersion driven by Conventional Commits (GitVersion.yaml):

  • feat: → minor bump
  • fix: / perf: → patch bump
  • ! or BREAKING CHANGE: → major bump
  • none: / skip: → no bump

Every push to main runs .github/workflows/cicd.yaml, which computes the version, builds, lints, publishes to npm, and creates a v<version> git tag + GitHub release. Requires an NPM_TOKEN repo secret.
